Short term (today and tonight)
issued at 326 am cdt Mon oct 15 2018
07z surface analysis indicated the initial cold front had pushed
into eastern il, with the secondary surge of colder air and
higher winds gusting over 20 mph nearing i-55. Isentropic lift
behind the front has produced a band of wet snow just northwest of
the CWA which is lifting northeast and will brush portions of
knox stark counties for the next hour or two. While some
scattered light rain or drizzle was occurring over the central
cwa, deeper moisture over the southern portion of the state has
been producing moderate showers south of i-70.

As the cold front continues to push east this morning, the
associated moisture and lift will depart our southeast counties by
mid morning. An extensive mid level cloud deck reaches back
through much of iowa, but short range models are consistent in
bringing clearing in from the northwest by midday west of i-55,
and across the remainder of eastern il through this afternoon. Due
to the tight pressure gradient and steeper low level lapse rates
behind the front, 20-25 mph wind gusts are expected. These winds
will supply a mid-november level airmass to the area, with highs
reaching the upper 40s to lower 50s.

Mostly clear skies are expected through tonight as the coldest
airmass of the season settles into the area. Lows of 30-32 are
expected north of a shelbyville to paris line, for the first
freeze of the season. Due to borderline temperatures have issued a
freeze watch for this area. Farther southeast, a frost advisory
has been issued where mins will drop into the mid 30s.

Long term (Tuesday through Sunday)
issued at 326 am cdt Mon oct 15 2018
a deep trough over the eastern u.S. And canada will keep northwest
flow in place across the region through Thursday. This will result
in dry weather with temperatures continuing to run 10+ degrees
below normal. A strong high pressure ridge shifting across the
midwest on Thursday morning will bring another cold night with
frost and freeze conditions possible. A shortwave ejecting out of
a southwest u.S. Trough towards the end of the week will
temporarily flatten the upper level flow and allow highs to reach
the upper 50s on Friday for the warmest day in the forecast. A
front associated with this wave will bring a low chance for
showers on Friday, however moisture return ahead the front is
weak. Another shot of cold air behind the front will keep dry and
well below normal temperatures in the forecast for next weekend.

Aviation (for the 12z tafs through 12z Tuesday morning)
issued at 515 am cdt Mon oct 15 2018
northwest winds will continue to gust 20-25 kts into this
afternoon in tight pressure gradient behind frontal passage. As a
high pressure ridge over the plains shifts east, winds will
quickly diminish around sunset. Current ifr MVFR ceilings will
show marked improvement toVFR this morning, as northwest flow
advects drier air into the region. Mostly clear skies will then
prevail through tonight.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
